this company that made one of my soon to be ex-clients websites uses and is going to be implimenting use of more of these "mini" sites they make. They expalined to me that its a copy of your site, with different content one ONE page and a different partial EMD or not at all url. this sounds VERY spammy / similar to what blog networks are. now is this still a viable backlink building option after the blog network slap 2 weeks ago, or is this spammy / similar enough that it could have negative effects towards rankings once they start to build more and more. thank you!
